Is it effective to use emergency contraception?

Yu Ting of Beijing Zizhu Pharmaceutical. The ingredient of Yuting is levonorgestrel, which is a simple progesterone. Has little side effect on human body and low failure rate. Because it is pure progesterone, if you get pregnant after taking it, it will not lead to fetal malformation and you can give birth normally. Now many obstetricians and gynecologists will ask what contraceptives they took before pregnancy. If it is a contraceptive composed of levonorgestrel, Yu Ting will advise against abortion. Many people think Yu Ting's two tablets are troublesome to eat. Yuting can eat two tablets together now. The contraceptive effect is the same. Clinical experiments have proved that the blood drug concentrations of the two methods are above the effective rate when taken once every 12 hours and two tablets are taken at the same time. Jin Yuting is a new generation of contraceptives developed and produced by Beijing Zizhu Pharmaceutical for different consumer groups. Jin Yuting is a component of levonorgestrel, and one tablet contains emergency contraception. You only need to take one tablet afterwards, and you can achieve contraceptive effect safely and effectively. Many people are used to eating diced glutinous rice, because they think it is a piece and more convenient. The ingredient of Houdingnuo is mifepristone. Mifepristone is a drug abortion with great side effects. Various adverse reactions often occur after taking it, and the physiological period is generally postponed. Taking it many times in a month can also cause symptoms such as massive bleeding. In addition, if contraception fails, it will lead to adverse reactions such as fetal malformation. Friends who take mifepristone ingredients should be careful. The side effects of emergency contraception are as follows: side effects of emergency contraception: nausea: the incidence of nausea in women who use emergency contraception is the highest, about 50%; Levonorgestrel followed, about 20%; Mifepristone is the lowest, about 6% ~ 7%. Nausea usually does not last more than 24 hours. Side effects of emergency contraception: vomiting: about 20% of women who use Yuzpe method for emergency contraception vomit; Levonorgestrel is about 5%; Mifepristone is about 1%. Taking medicine with food or before going to bed can reduce the occurrence of nausea and vomiting. If you vomit within 1 hour after taking emergency contraception, you should take 1 time as soon as possible. Side effects of emergency contraception: irregular uterine bleeding: Some women will have some X- drops of blood after taking the medicine, and generally do not need treatment, but users should be aware of this situation and do a good job in consultation and education before and after taking the medicine. Side effects of emergency contraception: menstrual changes: most women will have menstrual cramps on time, and some women's menstruation will be advanced or postponed. If menstruation is delayed for one week, a urine pregnancy test should be done to determine whether emergency contraception has failed. Side effects of emergency contraception: others: breast pain, headache, dizziness, fatigue, etc. These symptoms are generally mild and last no more than 24 hours. Patients with breast pain and severe headache can be treated with aspirin or other painkillers. In addition, the side effects of emergency contraception are: gastrointestinal discomfort, slight weight gain, mental stress, depression, skin spots and acne. Contraceptive pills may also cause breast cancer, cervical cancer, liver adenoma and so on. The second question: About half of the women will have symptoms such as low fever, dizziness, fatigue, lethargy, salivation, loss of appetite, liking sour food, aversion to greasy food, nausea and vomiting in the morning. In the early pregnancy, that is, "early pregnancy reaction", the reaction is the heaviest in the 8~ 10 week. This is the role of hormones in the development of pregnant eggs and the influence of neuroendocrine changes caused by maternal adaptation to fetal changes. At this time, the physiological function of pregnant women's digestive system is weakened, the secretion of gastric acid and pepsin is reduced, and the tension of gastrointestinal smooth muscle is reduced, so they like sour food and hate greasy food. Due to the prolonged gastric emptying time, pregnant women often feel full in the upper abdomen and burp. The sphincter of cardia at the entrance of the stomach is relaxed, and the acidic contents in the stomach can flow back to the lower part of the esophagus, resulting in heartburn. The increase of saliva secretion in pregnant women with nausea may be related to vagus nerve excitement. Pregnant women will also be constipated at this time. Therefore, in the first trimester, pregnant women should eat all kinds of light, delicious and digestible foods with reasonable and balanced nutrients. Don't eat too much food at once to prevent overeating. You can eat less and eat more. You can also replace dinner with fruits, milk, eggs and snacks, and increase the intake times to make up for the lack of quantity to ensure the necessary calories for physical activities. An empty stomach is more likely to cause nausea, so it is advisable to eat a small amount of snacks every 2 to 3 hours and before going to bed. Eat 1~2 slices of bread or biscuits before getting up, drink some hot milk, rest for a while and then get up slowly, so that morning sickness can be suppressed to some extent. Due to the influence of early pregnancy reaction, pregnant women feel unwell and exercise less, so there is no need to worry too much about insufficient food intake or panic about the change of eating habits. The separated psychological factors will reduce the degree of early pregnancy reaction to some extent. Generally about 3 months, the early pregnancy reaction will gradually reduce or disappear. Because of early pregnancy reaction, in the first three months of pregnancy, the weight of pregnant women sometimes not only does not increase, but will decrease. The average increase per person is about 1 kg, and it increases rapidly in the next few days. In a word, the first trimester is the stage of differentiation and development of fetal organs, and the physical growth is relatively slow, and the calorie consumption has not changed much compared with that before pregnancy, as long as we pay attention to the balanced intake of nutrients. During this period, we should eat more foods that are high in sugar and low in fat, light and easy to digest, and rich in vitamins, and eat less greasy and irritating foods. In the first three months of pregnancy, frequent urination and constipation will occur due to the gradual enlargement of the uterus and compression to the bladder and rectum, and some pregnant women will have frequent defecation without forming, which is a normal physiological phenomenon. Getting up early, going to the toilet regularly, exercising properly, eating fresh vegetables, especially vegetables and fruits rich in cellulose, and drinking a glass of milk or warm water early are all helpful to prevent or relieve constipation. Regular laxative habits are very important for health.
